DETAILED DESCRIPTION

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] Example 1

[0024] A quick-install liquid crystal display screen includes a display screen 1 and a connecting mounting base 2 arranged on the back of the display screen 1, wherein the connecting mounting base 2 is used to connect to a mounting surface 3 (such as a wall); the connecting mounting base 2 is provided with a connecting mechanism for quick installation between the mounting surface 3, and the connecting mechanism includes a first mounting groove 31 provided in the mounting surface 3 and a second mounting groove 21 provided in the connecting mounting base 2, a limiting member is provided in the first mounting groove 31, and a positioning member cooperating with the limiting member is provided in the second mounting groove 21, and the positioning member is movably provided in the limiting member and is limited by the limiting member.

[0025] When the present invention is in use, the connecting mounting base 2 on the back of the display screen 1 is connected to the mounting surface 3 (such as a wall). When connecting, the positioning piece on the second mounting groove 21 in the connecting mounting base 2 is extended into the limiting piece on the first mounting groove 31 in the mounting surface 3, so that the positioning piece is limited and fixed by the limiting piece, thereby quickly connecting the connecting mounting base 2 to the mounting surface 3 (such as a wall) without the need for screws to fix. Therefore, not only is the connection and fixation more convenient, but also the tedious and time-consuming disassembly work is saved; more specifically, in this embodiment, the limiting piece includes a support column 32, one end of the support column 32 is fixed to the inner side wall of the first mounting groove 31, and the other end is obliquely provided with a first limiting column 33; the free end of the first limiting column 33 is inclined toward the inner side of the first mounting groove 31 and is at an angle of 0.5 to 0.5 to 0.5 Acute angle; the positioning member includes a positioning column 22, one end of the positioning column 22 is rotatably arranged in the second mounting groove 21, and the other end is obliquely provided with a second limiting column 23; the free end of the second limiting column 23 is inclined toward the inner side of the second mounting groove 21 and forms an acute angle with the angle between the positioning column 22, and the free end of the second limiting column 23 is opposite to the inclination direction of the free end of the first limiting column 33, and the second limiting column 23 can be embedded in the first limiting column 33; in this way, when the connecting mounting seat 2 is connected to the mounting surface 3, the positioning column 22 can be used to move toward the support column 32, and the second limiting column 23 at the front end of the positioning column 22 can be clamped in the first limiting column 33 of the support column 32, and the mutual limitation between the first limiting column 33 and the second limiting column 23 is used to fix the connecting mounting seat 2 on the mounting surface 3.

[0026] In this embodiment, a positioning shaft 27 is provided in the mounting groove, and one end of the positioning column 22 is rotatably mounted on the positioning shaft 27 and can rotate around the positioning shaft 27; in this way, when disassembling, the positioning column 22 can be lifted to facilitate the separation between the positioning column 22 and the support column 32, thereby quickly disassembling the display screen 1.

[0027] In this embodiment, a limiting groove 25 is further provided on the connecting mounting seat 2 in the longitudinal direction, and the bottom of the limiting groove 25 is connected to the second mounting groove 21. A limiting spring 26 is provided in the limiting groove 25, and one end of the limiting spring 26 is connected to the top wall of the limiting groove 25, and the other end is connected to the top of the positioning column 22; this facilitates the longitudinal limitation of the positioning column 22 and maintains the stability of the positioning column 22; in addition, it is also convenient for the positioning column 22 to be inserted into the support column 32, and the range of rotation of the positioning column 22 around the positioning axis 27 is appropriately limited, so that after the positioning column 22 is inserted into the support column 32, the positioning column 22 can be quickly reset.

[0028] In this embodiment, a reset groove 28 is provided on one side of the second mounting groove 21, and the reset groove 28 is located below the positioning column 22. The positioning column 22 can be pushed upward by passing an external reset rod through the reset groove 28; specifically, after the reset rod passes through the reset groove 28 and extends into the second mounting groove 21, the reset rod is rotated to push the positioning column 22 upward. At this time, the positioning column 22 rotates appropriately around the positioning shaft 27, thereby separating the second limiting column 23 at the front end of the positioning column 22 and the first limiting column 33 at the front end of the supporting column 32, thereby releasing the positioning member and the limiting member, and then separating the connecting mounting seat 2 from the mounting surface 3, that is, the display screen 1 can be quickly disassembled through the reset rod without the need for other cumbersome tools or disassembly work, thereby improving the convenience of work.

[0029] In this embodiment, a pair of limit blocks 24 are provided on the side of the connecting mounting base 2 close to the mounting surface 3, and the pair of limit blocks 24 are respectively located on the upper and lower sides of the opening of the second mounting groove 21, and the pair of limit blocks 24 can be embedded in the first mounting groove 31. In this way, the limit blocks 24 can be used to be set in the first mounting groove 31 to provide a certain limit support between the connecting mounting base 2 and the mounting surface 3 to maintain stability during use.

[0030] In this embodiment, the lower limit block 24 can abut against the lower side of the support column 32, so that the lower limit block 24 can be used to support the support column 32, maintaining the support stability of the support column 32 after the positioning column 22 is connected to the support column 32.

[0031] In other embodiments, the support column 32 and the positioning column 22 are respectively provided with limiting holes for the first limiting column 33 and the second limiting column 23 to be inserted into the positioning column 22 and the support column 32 on the opposite side. This facilitates the first limiting column 33 to be inserted into the limiting hole on the positioning column 22, and at the same time facilitates the second limiting column 23 to be inserted into the limiting hole on the support column 32. In this way, the connection between the support column 32 and the positioning column 22 can be more stable, and the connection between the connecting mounting seat 2 and the mounting surface 3 can be more stable, that is, the connection between the display screen 1 and the mounting surface 3 is more stable, which not only ensures quick installation, but also has a stable connection and convenient disassembly.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
